Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667866, here are decompositions:

3 + 8667863 = 8667866
19 + 8667847 = 8667866
37 + 8667829 = 8667866
73 + 8667793 = 8667866
139 + 8667727 = 8667866
307 + 8667559 = 8667866
409 + 8667457 = 8667866
439 + 8667427 = 8667866

Showing the first eight; more decompositions exist.
